x86, UML: remove x86-specific implementations of find_first_bit
x86 has been switched to the generic versions of find_first_bit and find_first_zero_bit, but the original versions were retained. This patch just removes the now unused x86-specific versions. also update UML. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>
